To `ctZZ whom t may aon/cern: t i Be it `known that l, CHARLES J. CooK, a citizen of the United States, residing at St. Paul, in the `county of Ramsey and State of Minn esota,have invented certain new an d useful Improvements in EXtension-Tables; `and l I do 'declarethe following to be a full, clear, and exact description of the invention, such i as willen'able others skilled in the art towhich i it appertains to make and use the same, refer- Y enne being had to theaocornpanying drawings,` and to the figures of reference marked thereon, which form a part of this specification. i `My invention relates toimprovements in.` i extension-tables; `and the main object of the invention is to provide an extension-table in i `which all the leaves may at all times be con' vieiiiently contained inthe table, Whether the table be more or less extended or not extended at all. This; object I attain by the novel construction and arrangement of parts illustrated in the accompanying drawings, in

t which` l t Figure 1 is a top or plan view of my improved table in the closed position. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is a top n i `view of the table fully extended. Fig. 4 is a side view of Fig. 3 without legs. Fig. 5 is an enlarged cross-section von the line a a in Fig. e looking into the central section of the l table. The loose leaves 23 and 15 are, however,` in this `view shown in folded position, as when pushed into the central section of t the table, and the links andbars supporting the loose leaves-areshown` both in raised and lowered position.` Fig. 6 is an enlarged boti. torn view of the tablewith the legs in section neargthe table andone end sectionpushed intothe centralsectionofthe table. t

Referring to the` drawings by referencenumerals, l designates the centralsection of theftable. This section consistsof a fixed leaf and a frame composed of the-side pieces 2landi`cross-bars `3, secured to the lower edges thereof. To said crossibars 3 are secured by screwse the strips f5, `to which are again` secured the legs 6, either one legto each end, asinlower strip, or` one legin the middle,`as

The table may be" considered as consisting of a central section with a fixed leaf 1 and twoslidable frame-sections 7 and 8, supported by the legs 9. The frame-section 7 is formed with a pair of slidable bars 10, which are grooved sidewise to fit the dovetailed side rib 11 of the longitudinal guide-bars `12, xed upon the cross-bars 3 of 'the central frame. At the opposite sides of the' bars 12 slide likewise a pair of horizontal bars 13, projecting from the frame'section 8. Said end seo `tions of the frame carry 'each a fixed portion 14 of the table proper, which are always at a levelwith the centralfixed'leaf l.

The slidable frame-section carries a se-` :ries of narrow loose leavesl, 15, and 15b, each of which are secured on two bottom cleats 16, pivotally connected each by a pair of links 17 to the sliding bars 13, so that the top of the table may be gradually diminished by folding the links of one or more leaves l5, 15, and 15b toward the central section ofthe table, so that the links assume the horizontal position and the leaves 15 rest upon the bar 13 and slide into the central section, resting also upon the top of the bars 12. In order to thus insert the small leaves 15 into the central section, the end pieces 15d of the small leaves are secured to the leaves by hinges 18, which may be of metal or of suitable strong canvas, so that the ends may be folded, as in Figs. and 6, in which position they are held by the ledges 19 of the central frame until pulled out and elevated by raising the links, after which the table ispushed together, so that the dowel-pins 2O engage and hold the end pieces in horizontal plane. `The other end `frame 7 also has a few links 21, pivoted to the sliding bars and supporting two link-bars 22, on the top of which rest loosely the large loose leaf `23, which has also end pieces 23a hinged to it at 24 and adapted to fold in under the leaf and beheldfolded by the ledges 25, as shown in Fig. 5, until putin use by being elevatedon the link-bars 22 and jects downwardly an arm 27. These arms are secured together by a rod 28, from which extends about horizontally a longitudinal rod IAO O 29, guided in a vertically-slotted guide or staple 30 and provided at its under side with pass over the linkbars.

a ratchet-tooth 31, which when the bars 10 are pulled to their limit out of the central section engages the guide or staple`30, and thereby causes all the links 21 to rise from a horizontal to a vertical position, thereby bringing the link-bars 22 and the leaf 23 to full elevation by simply pulling the end section of the table out. When thisis done, the end section vis pushed back sufficiently to make the leaf 23 it properly between the leaves 1 and 14:. When the leaf 23 is to be lowered and pushed into the central section, theoperator pulls the end section outward about an inch, or so that the leaf 23 is set free from the dowel-pins. He then puts his hand under the end of the table, lifts the rod 29so that the tooth 31 clears the bottom of the staple 30, and pulls the rod outward so that the links fall horizontal,with the tops of the link-bars flush with the tops of the bars 10 and 12, so that the small leaves 15 may The leaf 23 is then moved so that it rests on the blocks 32, projecting-upwardly from the adjacent ends of the frame-bars 12. The leaf also rests on two blocks 33, projecting out of the frame-section 7 and having each'a dowel-pin 34, engaging a hole or indenture 35 in the under side of the leaf, so asto hold the leaf in place on said supporting-blocks while the end section is pushed into and pulled out of the central section.

36 in Fig. 6 represents stops to prevent the link-bars 22 from falling below the horizontal position, and 37 represents collars to prevent sliding of the rod 29 on the rod 28.

38 represents pins secured in the sliding bars 10 and 13, adapted to engage the terminus 39 of the grooves 40 in the cross framebars to limit the extension of the table. 4:1 represents grooves clear across said framebars to permit said pins to pass over the bars 3 which they are not to engage.

In a cheap grade of the table the rod 29 and staple 30 may be dispensed with, as the bar or rod 28 may be operated by the hand in both directions. Such and similar modifications I do not mean or wish to confine my invention to.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In an extension-table the combination with the central section 1 and its frame, of the guide or staple 30 at its bottom, the slidable section 7 having the loose leaf 23, the link-bar 22 and links 2l supporting same; two of said links having the arms 27 secured together by the rod 28 the rod 29,inserted in the staple and provided with the tooth 31 and being connected to the rod 28, substantially as and for the purpose set forth.

2. The combination with the central tablesection having a fixed leaf and the fixed guide-bars 12, of the sliding end section 8 having a series of leaves adapted to be lowered and pushed into the central section bestantially as and for the purpose set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.
